Almost all his items are a shipping of $17 - $17.50 but his other prices seems to be twice as much as they should be ... I could see $25 for the Hertz world but that is why it is still for sale
With his prices the extra Shelby GT sign and MPH magazine I have are priceless

Not my listing but if anyone is interested ... very hard to find
